Create Logger as field.
Added high-performance methods to Buffer for performing common operations like turning the contents of a Buffer (or just a slice of that Buffer) into an Integer or a Long, or slicing a Buffer into segments. These operations are useful when building codecs and other IO components that deal with ByteBuffers and want to keep copying of data to a minimum. It was also discovered through benchmarks how slow operations like parseInt() are and how much throughput can be gained by looking at each char individually.

Also started working on some test coverage of Buffer.
Add speed tests to measure the relative cost of various common parsing tasks.
